Treadmill Workout Ideas That Don't Feel Like A Total Slog

The treadmill doesn't have the best reputation. It's the machine so many of us default to when it's raining, when the gym is packed, or when we only have the energy for a walk and a bit of Netflix.

But the treadmill can be much more than a backup plan. With the right workout, it's an effective way to build endurance, improve your fitness, challenge your legs and make cardio feel far less repetitive than you're used to.

Why the treadmill deserves more credit

The treadmill has an image problem, and we get it. As a piece of gym equipment, it's not that glamorous (unless you've got a super fancy one), it doesn't have a bunch of people waiting to use it at the gym, and most of us only use it as a warm-up or when the weather isn't playing ball. Despite its reputation, though, treadmills are actually super effective, accessible and versatile.

Running or walking on a treadmill supports cardiovascular health, builds endurance and can help increase your daily energy expenditure. Because the belt has some give, treadmill workouts are generally easier on your joints than pounding pavement.

You're also fully in control. You set the speed, the incline and the duration, so there are no sneaky hills or traffic lights interrupting your flow, and you can easily plug and play the exact workout you want (which also makes it a great option if you're building your confidence). Treadmills work just as well for a steady 20-minute walk as a 5km jog, an incline hike, or a high-intensity sprint session. The range is huge.

Yes, it can get boring. Here's the fix.

The biggest treadmill criticism we hear is totally fair: staring at a wall or the exact same view while your feet go round and round can feel torturous after about five minutes. But that boredom usually isn't the treadmill's fault; it's what you're doing on the treadmill. Get on and press start with no plan, structure or goal, and of course it's going to drag.

Give your session some shape instead. Intervals, incline changes or turning the power off completely (more on that below) can turn the exact same 30 minutes into a completely different experience. If you'd rather follow a plan than build one from scratch, both Run Stronger and Ignite Running in the Sweat app include guided runs with audio coaching that talk you through every interval, whether you're on a treadmill or running outside. You just press play and follow along.

Different ways to use a treadmill

There's more than one way to train on a treadmill. Here are the main approaches worth knowing:

Steady-state cardio

Get on, hit start and move at a consistent pace for 20 to 45 minutes. This is usually a power walk (also called LISS or low-intensity steady-state) or a light jog. Great for active recovery, building your aerobic base, or getting your steps in when it's raining. The effort is manageable enough to do often without overtraining, and research shows moderate exercise 3 to 5 times a week can lower resting blood pressure and support heart health over time.

Incline walking

Raising the incline even a few degrees makes a huge difference. Research published in BMC Geriatrics found that a 10% incline increased net metabolic energy cost by nearly 23% compared to flat walking, meaning you're getting significantly more out of the same time on your feet. You'll feel it a lot more in your glutes, hamstrings, quads, and calves, but being a walk, it's still joint-friendly.

Interval training (HIIT)

Alternating high-effort bursts with recovery periods is time-efficient and well supported by research. A 2024 narrative review found HIIT can improve vascular function, blood pressure, cardiac output and heart rate variability. It's demanding on your body though, so 2 to 3 sessions a week is plenty.

Tempo runs

A tempo run is a sustained, comfortably hard run (around 20 minutes) at roughly a 7 out of 10 effort. It's hard enough that holding a full conversation is difficult, not so hard that you're hanging on for dear life. Research shows the main payoff is a higher lactate threshold, which basically means your fitness and stamina improve. A tempo run feels less brutal than doing max-out sprint intervals, but more purposeful than a casual jog.

Deadmill sessions

These are hard, but in the best way. Turn the treadmill off, hold the handles, lean forward and use your own strength to push the dead belt around. It's a less conventional way to use a treadmill, but as soon as you start, you'll get it. The burn in your lungs, abs and legs is intense. Try an extended deadmill walk, or do short running intervals. Deadmill training isn't suitable on every treadmill, so always check your machine's manual first or ask a gym staff member, and start conservatively until you're comfortable with the movement.

Treadmill workouts to try

Ready to mix things up? Here are five treadmill workouts you can save for your next session, whether you're after a gentle incline walk or a sweaty sprint workout.

The 12-3-30 walk (30 mins)

Set the treadmill to a 12% incline and walk at 3 mph for 30 minutes. That's it. It sounds too simple to work, but this workout went viral for a reason. The steep incline makes walking genuinely challenging, and because it's low-impact, it suits a wide range of fitness levels. If 12% feels like too much to start, drop the incline and build up gradually.

Beginner interval session (20 mins)

• Warm up: 5 minutes easy walking

• Work: alternate 1 minute jogging with 2 minutes walking, repeated 4 times

• Cool down: 5 minutes easy walking

Intermediate to advanced HIIT session (25 mins)

• Warm up: 5 minutes easy jog

• Work: 30 seconds at near-max sprint effort, 90 seconds easy jog, repeated 8 times

• Cool down: 5 minutes walking

Deadmill HIIT session (18-25 mins)

• Warm up: 5 minutes easy jog

• Work: 20-30 seconds deadmill sprint (treadmill turned off), followed by 30-60 seconds walking or rest to get your breath back, repeated 8-10 times

• Cool down: 5 minutes walking

Incline pyramid (30 mins)

Start at 0% incline and increase by 2% every 3 minutes until you hit 10%, then bring it back down the same way. Do it as a walk or a run, keeping your speed consistent throughout. It's a great way to challenge yourself without committing to a flat-out sprint.

Want more structure than a one-off session?

If you'd rather not think about pace or timing at all, follow a guided run instead. Both Ignite Running and Run Stronger in the Sweat app include audio coaching that tells you exactly when to speed up, slow down or recover, whether you're on a treadmill or running outside.

Log it, track it, celebrate it

The best treadmill workout is the one you'll actually come back to. Whether you're walking, running or tackling intervals, consistency is what really builds your fitness over time.

If you're ready for more than a one-off workout, Sweat's Ignite Running and Run Stronger programs take the guesswork out of training with guided runs, strength sessions and a progressive plan you can follow on the treadmill or outdoors. And if you're doing your own thing, you can still log every treadmill session in the Sweat app so your progress counts toward your weekly training goals.
